Eurospher 100 CN packing material can be universally used in different polar modes (normal and reversed phase LC). Due to the quick equilibration time of the CN bonded phase, it is the best choice for gradient elution in normal phase mode. Eurospher 100 CN can be used as a less polar alternative to Eurospher Si. The material is typically preferred for compounds with double bonds and for cyclic antidepressants.

ProntoSIL CN is a cyano-propyl bonded phase. It can be used in normal phase mode and reversed phase mode. In RP mode, the application area of ProntoSIL CN is the separation of strong basic solutes. In NP-mode, the ProntoSIL CN support offers a complementary selectivity to the other NP phases Silica, Amino and Diol. Due to the quick equilibration time of the CN bonded phase it is the best choice for gradient elution in NP mode. The CN bonding is available in 120 Å and particle sizes of 3 μm and 5 μm.
